ROLLING-MILL.

SPECIFICATION forming part of Letters Patent No. 602,864, dated April 26, 1898.

Applioationiiled September 18, 1897. Serial No. 652,204. (No model.)

To all whom it may concern.-

Be it known that I, WATT D. MATTHEWS, a citizen of the United States, residing at Pittsburg, in the county of Allegheny, State of Pennsylvania., have invented a certain new and useful Improvement in Rolling-Mills, of which the following is a specication, reference bein ghad to the accompanying drawings.

This improvementis designed mainly to render rolling-mills more convenient in use; and it consists mainly in a new mode of adjustment of the rolls and in a novel construction of the foundation, whereby the scale formed in rolling is readily removed.

To these ends the invention consists in the construction hereinafter more particularly described and then definitely claimed at the end hereof.

In the accompanying drawings, Figure 1 is a front view of a set of rolls constructed ac cording to my improvement. Fig". 2 is a central vertical cross-section. Fig. 3 is a plan of a foundation. Fig. et is a horizontal section Fig. 5 is a vertical cross-section through the center of the housing, on a larger scale.

Referring now to the details of the drawings by figures, 1 is the foundation, of brickwork, in front of which is a long trough 2. Above this is the base 3, having perforations 4, which are over the chutes 5, leading into the trough 2 and formed in the brick foundation. This base forms the supports for the housings 6, which are of the usual or any suitable form and surmounted with the usual caps 7 and securing devices 8. In these housings are mounted the rolls 9, having journais 10, running in bearings 11, the adjustment of which forms the main feature of my invention. Each of these bearings, except the top and bottom, has an inclined groove 12, in which slides a Wedge 13, havinga groove 14, in which works a ball 15, formed on the end of a bolt or set-screw 16, provided with a square head 17, by which it may be turned, and a washer 1S and lock-nut 19 to hold the bolt when the proper adjustment has been obtained. In lieu of the square head on the bolt any other known or convenient device for turning it may be used.

The nuts in which the bolts work may be secured in the housing in any desirable Way;

but I prefer to make them of dovetail shape and set them in dovetailed recesses in the housing.

The arrangement of my scale-chutes 5 and the trough 2 will be found to be very convenient. Under the system now practiced the scale accumulates in a recess in the foundation immediately un der the rolls,which recess has to be cleared several times a day; but with my chutes and trough the scale will run down through the chutes with the water dripping from the rolls and may accumulate for a week or two without any inconvenience resulting therefrom, Vthe water passing off through the spout 2l to a sewer, and the scale can then be readily removed from the trough without interfering with the working of the rolls.

I do not wish to limit myself to the precise construction shown, as it is evident that my adjusting device may be used in dierent ways without departing from the spirit of my invention.

1. The combination of ajournal-bearing, a housing therefor, provided with a threaded hole for a screw, and a wedge having a slot wider inside than at its edge, a screw whose end substantially fits said slot and works in said threaded hole, whereby the turning of the screw will either push in the wed ge or retract it, substantially as described.

2. The combination in a rolling-mill of a foundation for the same provided with a series of chutes 5 below the rolls to deliver the scale therefrom, solid supports between said chutes arranged under the housings to sustain the sets of rolls, a perforated plate 3 running lengthwise over the foundation to bind the same, and a trough arranged beneath said chutes to receive the scale from said chutes and provided with an outlet for the Water entering the trough with the scale, all substantially as described and shown.

In testimony whereof I aihx my signature, in the presence of two witnesses, this 11th day of September, 1897.

WATT D. MATTHEWS.
